CAA RONI SP1 Springfield XD 9mm / 40 S&W Pistol Carbine Chassis Kit w/ Adjustable Stock

[Great-Kazoo]

Mission adaptable nice and your XD is on you hip for backup in case you drop/lose or run out of ammo on your SBR.

God No, XD 4 me P99, M&P9c or 229, locked and loaded. 10-30rd sten mags weigh more than i do.
The 22 and 9 units can crank out spent cases as fast as you can pull the trigger. Was hitting steel out @ 173ish with the 9 and keeping the berms head down with the 22

I guess you'd have to get this one to avoid the NFA SBR Tax Stamp...

But, then again, might as well just buy another firearm after the total cost...
